Application filed July 6,

My invention relates to guards for the protectionof windows andcontemplates the utilization of demountable bars associated with meansfor mounting and locking the bars in operating position and with meansfor storing the bars when not in service.

One object of my invention is to design the mounting means for the barsso that the same.are hardly noticeable'and require but a slight changeinthe meeting check rails of the top and bottom sashes to receive themwhen applied to existing windows, and which are capable of being builtinto new window frames so as to take the place of the parting stripbetween the runways for the upper and lower sash.

Another object of my invention is to pro- Vide these bar mountingmembers with racks to receive and hold the demounted bars at the bottomof the window.

A further object is to design the bars so that they can be readilyinterlocked with their mounting members by the operation of one commonlock bar and when thus locked in position,access cannot be had to unlocksame without breaking the window.

My invention further comprises the novel details of construction andarrangements of parts, which in their preferred embodiment only, areillustrated in the accompanying drawings which form a part of thisspecification, and in which Fig. 1 is a front elevation with a. windowframe equipped with my improved guide bars shown in operating positionand in demounted position in dotted lines.

Fig. 2 is a cross-sectional view taken on the line 22 of Fig. 1.

Fig. 3 is an enlarged view broken away of the bars showing theirmounting means partly in elevation and partly in section.

Figs. 4 and 5 are detail views illustrating the latch for holding thelock bar in operation or idle'position.

Similar reference numerals refer to similar parts throughout thedrawings.

In the embodiment of my invention illustrated, I show conventionally awindow frame having an upper sash 1, a lower sash 2, with the runwaysfor said sashes separated by a parting strip 3 throughout their upperportions and by the bar mounting members 7 and 8 which continue to thestool 6 of the window frame. The bottom check rail 4 of the upper sashand the top check 1926. Serial No. 120,598.

rail 5 of the lower sash are cut away at each end, where necessary, toaccommodate the members 7 and 8, such cutting being necessary where theguard is applied to old windows, but it may be avoided in new windows byhaving the mounting members 7 and 8 to correspond in cross sectlon withthe part ing strip.

The bar mounting member 8 is preferably formed of tubular metal havingthe width of the parting strip 3 and having substantial depth so thatthe apertures 9, arranged at suitably spaced intervals in its inneredge, are adapted to receive the reduced ends 10 of the "uard bars 11with sutficient overlap of said ends in the mounting member to preventthem being pulled out. This tubular member 8 is secured in any desirablemanner to the window frame as by wood screws 1 12 inserted through theapertures 9 and through the inner wall of the member and screwed intothe window frame.

. The mounting member '7 for the other end of'the bars is also formed'oftubular metal similar in cross section to the member 8 and similarlymounted. At corresponding int-ervals in this member 7 opposite theapertures 9 I provide notches 13 which extend from the outside wallacross the inner end wall and partway across the inside wall, thuspermitting the ends 14 of the rods tobe moved into position with theholes 15 in such ends disposed in alignment within the tubular member 7.In the space between the ends 14: of the bars and the inner wall of themember 7 which is screwed to the frame, I introduce a lock bar 16 havingfor each bar 11 an offset downturned angled lock pin 17 adapted toproject through the hole 15 in its respective bar. The upper end of thislook rod is out-turned at 18 and adapted to engage in one or the otherof two holes 19 or 20 in a plate 21 attached to the parting strip 3,these holes permitting the lock bar to be set in operative orinoperative position.

At the bottom of the members 7 and 8 I provide means to rack thedismounted guard bars 11, such means preferably taking the form of aninside notch 22 merging into a vertical slot 23 in the inner edge of themember 8 at its base, and a vertical slot 24 at the base of the innerwall of the member 7. By this arrangement the bars 11, as they aredismounted, can have their ends 14 inserted in the slot 24 and theirother ends infit Having attached the uiountingl; inen'ihers 7i and 8 tothe Window Frame in the manner described, the guard liars ll are put inplace by inserting their reduced ends it) in the apertures 9 in themounting iuemher 8 and then shifting}; the end .l-lof each through anotch 13 into position to reg il'Cl' with the lock pins 1'? oil? thelock bar, which at the time will he engaged in the upper hole .20, whichholds immerative position.

it in hen all oi. the bars 11 ha Ye heen thus assembled, the lock har isdisengaged from the upper hole 20 by bending it outwardly and then it ismoved downwardly until the pins 17 interlock in the holes '15 of theseveral hars TL after which the loeh bar is engaged in the lower hole1!) which prevents it 't'ri'uu heing raised hr anyone on the outside ofthe Window without hreahing the. glass.

This arrangement thus permits the hars to be readily put up at night andtaken down and racked during the day when they might be ohjectionahle orunsightly.

Having thus described my inrentiou, What I claim as no and desire tosecure b'y' Lotters Patent, is l 1. A Window guard con'iprising aplurality of bars and inountii'ig' elements for said bars disposed inthe plane of the parting strip between the window sashes, said elementscomprising sockets to receive the ends of the bars, and a locking devicehoused in one of said elements and momhle into position to lock orrelease all of said bars simultaneously, said bar mounting elements heing provided at their bases with rack means to hold the dismounted.guard bars.

2. A. Window guard (JOITlIH'iSlllg a pluralily of separate bars andmounting elements therefor comprising at one side an element providedwith apertures to receive one end of the bar and at the other side witha tuhular element lraving notches tor the reception of the other end of.the bars, and a multiple lock har lor all ol the guard bars slid ahle insaid tubular element the multiple lock har projecting above, the tubularelement and lower sash and being associated with means on thepart-inpstrip to hold it. in operative or inoperative position. i

A. Window guard comprifng a plural ity of bars, each reduced atone endand at the other end flattened and perforated a tubular bar supportadapted to be mounted at each side in the plane of theparting strip,

one bar support having holes in its inner wall to receive the reduced.end oil the guard bars and the other support having notches in its innerside and inner end wall to receive the flattened end of the guard bars,and a multiple lock element vertically slidahle in said latter supportand adapted to project through the perforations in the ends orli theguard bars to lock them in assembled position in the bar supports.

In testimony whereof I alfix my siglature.
